Motor racing: Red Bull dismiss Vettel tantrum report

(REUTERS) - Formula One champions Red Bull recognised on Saturday they were well behind rivals in pre-season testing but dismissed reports that Sebastian Vettel had "thrown a hissy fit" about the situation.

The four-time drivers' champion and his team have suffered a string of setbacks due to the new Renault power unit and the problems continued in Bahrain on Saturday with the German breaking down on his first lap of the day.

He helped marshals push the stricken RB10 back to the garage.

Red Bull team principal Christian Horner told Sky Sports News that speculation Vettel had thrown a tantrum when he first tested the car back in January was "complete and utter rubbish".
